Abstract:
A system evaluates image quality in an image generating system in a manner that accounts for the interaction of the calibration tools used to evaluate and correct image quality in the image generating system. The system includes a test pattern generator configured to generate an image with an image generating system, an image capture device configured to generate a digital signal corresponding to the generated test pattern, an image evaluator configured to process the digital signal to detect and correct anomalies detected in the generated test pattern, a plurality of calibration tools, each calibration tool being comprised of at least one test pattern, at least one set of detection criteria, and at least one set of anomaly correction parameters, and a controller configured to select the calibration tools for operation of the test pattern generator and the image evaluator in accordance with a predetermined sequence that attenuates changes arising from application of correction parameters of one calibration tool upon a later selected calibration tool.
